bug#20900: 25.0.50; C-u - C-t should move point backward to have a usefully repeatable command

[Nicolas Richard]

In a line like this:
aaaaaaaaxy
with cursor on y (i.e. point is between x and y).

Hitting C-u - C-t moves the 'x' backwards, but the cursor stays on 'y'.
Thus hitting C-x z is mostly useless here. I expected cursor to move
backward too.

In fact this is a regression introduced by

(I'm going through old bug reports that have unfortunately not gotten
any responses.)

I'm unable to reproduce this bug in Emacs 27, so I'm guessing that it's
been fixed in the intervening years, and I'm closing this bug report.
If it's still present, please reopen.
